Tolerability and Efficacy of a Medical Device Repairing Emollient Cream in Children and Adults with Mild to Moderate Atopic Dermatitis

The Real-World Effectiveness and Tolerability of a Soothing Cream Containing the Postbiotic Aquaphilus dolomiae Extract-G2 for Skin Healing

INTRODUCTION

In vitro and pre-marketing clinical data have shown the healing properties of a postbiotic extract from Aquaphilus dolomiae (ADE-G2). The effectiveness and tolerability of an ADE-G2-based cream were therefore evaluated for the management of minor skin impairment and wound healing in a large population of subjects in routine clinical practice.

METHODS

A real-world, international, pre-post comparative study was conducted in infants, children, and adults with various types of superficial skin impairment who used the study product daily for around 3 weeks according to their dermatologist's advice. Immediate and follow-up changes in dermatologic signs and symptoms were assessed through clinical scoring. User satisfaction, overall product effectiveness, and tolerability were also evaluated. Analyses were performed in the whole study population and in subject subgroups according to skin impairment type and age.

RESULTS

Overall, 1317 subjects (83.1% adults, 72.0% female) were included. Dermatologists reported effectiveness and "good" or "very good" tolerability of the cream in 93.8% (1221/1302) and 98.5% (1278/1297) of subjects, respectively. Immediate symptom relief after the first application was reported by 88.3% (849/962) of subjects. After several weeks of regular use (16.7 ± 11.6 days), dermatologic signs and symptoms significantly improved in the whole study population and in the subgroups, with mean decreases in severity scores ranging from -34.5% to -92.5% (p < 0.0001). The smallest improvements were found in subjects with oncologic treatment-related skin impairment. At study end, most users (> 95%) were "very satisfied" or "satisfied" with the cream and found that skin healing was rapid and of good quality.

CONCLUSION

The ADE-G2-based cream proved to be effective and well tolerated in real-life conditions for the management of minor skin impairment in a large and varied cohort of subjects. This product, used as a standalone or adjunctive regimen, can help accelerate the healing of various types of superficial skin impairment.

A Review of Moisturizing Additives for Atopic Dermatitis

Atopic dermatitis, the most common form of eczema, is a chronic, relapsing inflammatory skin condition that occurs with dry skin, persistent itching, and scaly lesions. This debilitating condition significantly compromises the patient’s quality of life due to the intractable itching and other associated factors such as disfigurement, sleeping disturbances, and social stigmatization from the visible lesions. The treatment mainstay of atopic dermatitis involves applying topical glucocorticosteroids and calcineurin inhibitors, combined with regular use of moisturizers. However, conventional treatments possess a certain degree of adverse effects, which raised concerns among the patients resulting in non-adherence to treatment. Hence, the modern use of moisturizers to improve barrier repair and function is of great value. One of the approaches includes incorporating bioactive ingredients with clinically proven therapeutic benefits into dermocosmetics emollient. The current evidence suggests that these dermocosmetics emollients aid in the improvement of the skin barrier and alleviate inflammation, pruritus and xerosis. We carried out a critical and comprehensive narrative review of the literature. Studies and trials focusing on moisturizers that include phytochemicals, natural moisturizing factors, essential fatty acids, endocannabinoids, and antioxidants were identified by searching electronic databases (PubMed and MEDLINE). We introduce the current knowledge on the roles of moisturizers in alleviating symptoms of atopic dermatitis. We then further summarize the science and rationale of the active ingredients in dermocosmetics and medical device emollients for treating atopic dermatitis. Finally, we highlight the limitations of the current evidence and future perspectives of cosmeceutical research on atopic dermatitis.

A Novel Vitamin E TPGS-Based Formulation Enhances Chlorhexidine Bioavailability in Corneal Layers

Keratitis is a severe condition characterized by inflammation of the cornea following a local trauma. The most common ocular disease is the bacterial one, which requires an antibiotic treatment. The major limitation of this therapy is the resistance of the antibiotic. For this reason, alternative procedures have been developed and consist of antimicrobial molecules. One of the most used is the chlorhexidine gluconate, which has shown activity versus Gram-positive and Gram-negative bacteria and fungi. In addition to its efficiency, chlorhexidine shows low toxicity levels for mammalian cells and is a low-cost molecule. Despite its multiple benefits, chlorhexidine, if used at concentrations higher than 0.02% (w/w), can cause local eye irritation. Additionally, its poor penetrability through the cornea makes necessary frequent instillation of eye drops for a prolonged time. Due to these limitations, alternative drug delivery strategies are required. Here, we report a novel formulation based on the combination of d-alpha-tocopherol polyethylene glycol 1000 succinate with chlorhexidine, which results in higher accumulation of the drug in human corneas measured by liquid chromatography and strong antimicrobial activity. Moreover, this formulation does not cause any toxic effect on human cells and is well tolerated by rabbit eyes. Therefore this novel formulation represents a good candidate for the treatment of keratitis that overcomes the risk of antibiotic resistance.
